Who I have the same questioned this topic

Once again, thank you for responding. The problem started a couple of

months ago. The volume up/down control is not stuck.

The issue is that the sound setting automatically and uncontrollably

changes from "Normal," or ringtone, to "Vibrate Only." Simultaneously, my

phone makes a loud "Pop" sound, and a pop up of my sound settings appears

on the screen. The pop up first notifies me the setting has changed to

vibrate without ringtone, and then a second pop up appears showing the

volume settings for ringtone, notifications, etc. I cannot go into the pop

ups to change the settings back. I have to hit Cancel at the bottom of the

screen, leave what I am doing, go into settings for sound control on my

phone and reset them where I want. Trouble is just as soon as I return to

what I am doing, or even if I try to turn off the screen, this happens all

over again, and continues uncontrollably.

Can you be of any help, or not?

Thanks.
